TNMG 160404 T5105 turning insert by Tungaloy — CVD‑coated carbide, triangular ISO insert

The TNMG160404 T5105 is an ISO‑format triangular turning insert engineered for high‑speed machining of cast iron under stable setup conditions.

• CVD‑coated carbide T5105 for cast iron
• ISO TNMG 160404 triangular insert, 16 mm size
• 0.4 mm nose radius for fine surface finish
• Double‑sided chipbreaker with cylindrical hole for secure clamp

Optimised wear resistance for high‑speed cast iron turning

The CVD‑coated carbide grade T5105 combines a hard coating with a tough substrate to provide controlled wear progression when machining cast iron at elevated speeds. This composition reduces flank wear and extends usable life, which in turn lowers machining costs per component. CVD coating is a chemical vapour deposition layer applied to improve abrasion resistance; in practice, this means the insert keeps a sharper cutting edge for longer and maintains dimensional stability on critical turning operations. The result is predictable tool change intervals and reduced rework.

Seamless compatibility with ISO tooling for quick integration

Supplied in the ISO TNMG format, the insert fits standard triangular holder pockets with compatibility determined by shape, relief angle, tolerance class, fastening method, size and thickness. The triangular geometry and cylindrical hole enable positive clamping in most external holders or boring bars designed for TNMG inserts, while the plate thickness of 4.76 mm supports rigid seating. This standardisation facilitates rapid replacement and minimal setup time, so machining cells can be returned to production quickly after tool changes.

Consistent surface finish and chip control in productive setups

The double‑sided chipbreaker geometry and 0.4 mm nose radius support a balance between surface finish and material removal rate on external and internal turning operations. A small radius improves profile accuracy and reduces the need for finishing passes when the machining setup is stable; conversely, the chipbreaker design aids predictable chip formation and evacuation when cutting cast iron. For best results, the insert performs under controlled cutting parameters and rigid fixturing, delivering repeatable surface quality and machining stability.

FAQ

What materials is this insert suitable for? The TNMG160404 T5105 insert is designed primarily for machining cast iron and is optimised for high‑speed conditions when a stable setup is used.

Which holder types are compatible with this ISO insert? Compatibility is achieved with standard ISO TNMG holders and boring bars that accept triangular inserts; the seat form, relief angle and clamp system must match the TNMG 160404 dimensions.

What advantages does the T5105 grade provide? T5105 (CVD‑coated carbide) offers improved abrasion resistance and predictable wear characteristics, enhancing tool life and process stability for cast iron turning.

How does the 0.4 mm nose radius affect surface finish? A 0.4 mm nose radius helps produce a finer surface finish and accurate profiles while keeping the cutting forces moderate, which is beneficial in stable turning setups.

Is the insert reversible and how many cutting edges are available? The double‑sided triangular design provides multiple usable cutting edges per insert, enabling economical use of each indexable plate.
